BRUSH ATTACHMENT FOR CAN-CHHMPHNGI WlI iGl-lll iES.

SPECIFICATION forming part of Letters Patent No. '789A06, dated May 9, 1905.

Application filed September 3, 1904. Serial No. 223,242.

To all whom it nmy concern.-

Be it known that INVILLIAM BoLDnNwnoK, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Brush Attachments for Can-Crimping Machines, of which the following is a specification.

The main object of my invention is to provide an improved form of brush-holding device for attachmentto can-crim ping machines, whereby the cans may be sealed and cleaned by a single operation. I accomplish this object by the device shown in the accompanying drawings, in which-- Figure 1 is an elevation of a can-crimping machine provided with a brush attachment constructed according to my invention. Fig. 2 is a top plan of the crimping-arm and brush attachment removed from the other parts of the machine. Fig. 3 is a side elevation of the same. Fig. 4 is a front elevation of the same.

The can-crimping machine consists of a frame 1, provided with a pair of chucks 2 and 3, rotatably mounted in the frame 1 in alinement with each other, together with mechanism for rotating the chucks and the crimping and cleaning attachment, which will be hereinafter described. The upper chuck 3 is usually driven by the mechanism, while the lower chuck runs idle. The lower chuck forms a support for the can and may be moved vertically by treadle mechanism (not shown) for causing the can to be gripped tightly between the chucks 2 and 3. In the device shown the crimping-roller at is journaled on a vertical axis on a lug 14: on a horizontal member or arm 5, which is pivotally mounted at 6 on a vertical axis in the frame 1. The arm 5 is swung on its pivot 6 to bring the crimping-roller at into contact with the flange of the cover of the can. The movement of the arm 5 toward the axis of the rotating chuck 3 is limited by the adjustable stop 7, which engages a part of the frame and insures a uniform depth to the crimping. The brush-holder 8 is provided at its upper end with a jaw 9, which spans a part of the arm 5 and is rigidly held thereon by means of setscrews 10. The brush-holder also has a part extending at right angles to the arm 5 and provided with an elongated slot or socket 11, in which one or more brushes may be secured by set-screws 12. One brush 13 is shown in position in the holder 8; but the holder is made of considerable length, so that a plurality of brushes may be held or others of different lengths may be inserted to suit cans of different sizes. The bristles of the brush 13 extend substantially at right angles to the axis of the crimpingroller 4:, and the brush is so located as to engage the can when the crimping-roller 4: is in contact with the same. The outward throw of the arm 5 is limited by a flexible strap 15, which is secured to the lower end of the brushholder 8 and also to the frame 1.

In the operation of the device shown the can is rapidly rotated, and the crimping-roller 4: is forced into contact with the cover of the can by the inward movement of the arm 5. This movement also brings the brush 13 into contact with the can and cleans the surface of the can. The brush may be readily adjusted toward the can to compensate for wear on the bristles. Other features of the operation will be readily understood from the foregoing description.

It will be seen that some of the details of the device shown may be altered without departing from the spirit of my invention.

\Vhat claim as my invention, and desire to secure by Letters Patent, is'

1. In a can-crimping machine, the combination of a frame, a member movably mounted in the frame and having a crimping-roller journaled thereon, and a brush secured to said member at one side of the crimping-roller and adjacent thereto and having its bristles disposed transversoly of the axis of the roller, substantially as described.

2. In a can-crim ping machine, the combination of a frame, a member movabl y mounted in the frame and having a crimping-roller journaled' thereon, and a brush secured to said member at one side of the crimping-roller and adjacent thereto and having its bristles disposed transvcrsely of the axis of the roller, said brush being adjustable transversely of the crimping-roller, substantially as described.

In a can-crimping machine, the combinaback of a brush; a brush having its bristles disposed transversely of the axis of the crimp- I5 ing-roller and having its back seated in said slot; and set-screws extending into said slot and bearing against said back for adjustably securing the brush, substantially as described.
